摘要
为了减少长链全氟和多氟烷基物质(Per-and polyfluoroalkyl substances,PFASs)的环境危害或规避监管,制造商开始大规模生产和使用短链PFASs作为替代品,导致环境中短链PFASs数量激增.与传统的长链PFASs相比,短链PFASs的生物累积性和潜在毒性可能相对较低,但仍表现出极强的环境持久性和更强的远距离迁移能力,未来可能会逐渐发展为水环境中PFASs的主要成分.因此,研究去除水环境中短链PFASs的问题迫在眉睫.本文总结了水体中短链PFASs的最新污染现状,分类概述了不同吸附剂去除水中短链PFASs的应用与效果,对吸附水中短链PFASs的影响因素进行了系统性归纳,以期为设计新型吸附材料去除水环境中的短链PFASs提供思路.
In order to reduce the environmental hazard of long-chain per-and polyfluoroalkyl substances(PFASs)or to avoid regulation,manufacturers have initiated large-scale production and usage of short-chain PFASs as substitutes,resulting in a proliferation of short-chain PFASs in the environment.While short-chain PFASs may be relatively less bioaccumulative and potentially less toxic than traditional long-chain PFASs,they still exhibit extremely strong environmental persistence and enhanced long-range transport.And they may gradually develop into a major component of PFASs in the aqueous environment in the future.Hence,it is urgent to study the removal techniques of short-chain PFASs from water.In this review,the pollution status of short-chain PFASs in water was summarized.Meanwhile,the applications and effects of different adsorbents for the removal of short-chain PFASs in water were classified and the influencing factors of short-chain PFASs in adsorbed water were systematically summarized.This review will provide some inspirits for designing new adsorbent materials for the removal of short-chain PFASs from environmental water matrix.
